Lectures and Commentaries on Srimad Bhagavatam Canto 1, made in Vrindavan (India)
The purpose of Śrīmad Bhāgavatam is to glorify the Supreme Absolute Truth, known as Śrī Kṛṣṇa, for the benefit of the suffering humanity. Śrī Vyāsa himself calls this Purāṇa the ripened fruit of the Vedic tree and compares it to the personification of rasa, or devotional relish. It is to be tasted by the rasikas, the connoisseurs of rasa, and relished by the sahṛdayas, the sober-hearted people or those whose hearts are imbued with sattva (SB 1.1.3)
Our life is running on these two currents of raga and dvesha. It is the same river, but sometimes we are on the love side of the river bank and sometimes we are on the hate side. But the river is only one. There is only one reality. It is our mind that makes a duality of the reality. As soon as something enters our mind, we automatically divide it into either like or dislike. When your mind is running in these two grooves, then you cannot see the reality.
